Description

Technical Field

[0001] This utility model relates to the field of soldering machine technology, and in particular to a dual-station automatic soldering machine with a self-inspection function for solder joint quality. Background Technology

[0002] In the electronics manufacturing industry, automatic soldering machines are key equipment for soldering circuit boards and electronic components. In order to improve work efficiency, dual-station soldering machines have also emerged. The two stations are usually in parallel production mode, that is, each completes the soldering independently. However, when a soldering abnormality occurs at one station, the abnormal workpiece needs to be removed manually and placed in the other station for resoldering. This process will cause production interruption, and manual transfer is prone to workpiece positioning deviation, causing the resoldered solder joint to be misaligned with the original solder joint, further increasing the product defect rate.

[0003] Based on the above situation, it is necessary to design a dual-station automatic soldering machine with a self-inspection function for solder joint quality to solve the above problems. Utility Model Content

[0004] This invention provides a dual-station automatic soldering machine with a self-inspection function for solder joint quality, in order to solve the problem that in the prior art, when abnormalities occur in the soldering process, timely resoldering cannot be performed.

[0005] The technical problem solved by this utility model is achieved by the following technical solution: A dual-station automatic soldering machine with self-inspection function for solder joint quality includes a frame with two multi-axis motion mechanisms on it. Each of the two multi-axis motion mechanisms has a main soldering mechanism and a backup soldering mechanism. The machine also includes a first vision self-inspection component, a workpiece transfer mechanism, and a main control unit. The workpiece transfer mechanism, mounted on the frame, is used to transfer workpieces from the main soldering station to the backup soldering station. When the main control unit receives a signal from the first vision self-inspection component indicating an abnormal solder joint quality at the main soldering station, it controls the workpiece transfer mechanism to move the workpiece to the backup soldering station. Simultaneously, it activates the backup soldering mechanism at the backup soldering station to resolder the abnormal solder joint on the workpiece.

[0006] Preferably, the main control unit further includes a counting module and an alarm module. The counting module is used to count the number of times the standby soldering station is started within a unit of time. When the number exceeds a preset threshold, the control system triggers the alarm module to issue an alarm signal.

[0007] Preferably, the workpiece transfer mechanism includes a placement tray slidably connected to the frame and a telescopic member disposed on the frame with its movable end connected to the placement tray.

[0008] Preferably, the main control unit further includes a synchronization control module, which is configured to: when the main control unit controls the multi-axis motion mechanism of the main soldering mechanism to perform soldering action, simultaneously send the same motion parameter instructions to the multi-axis motion mechanism of the backup soldering mechanism to achieve synchronized action between the two.

[0009] Preferably, the frame is provided with feedback components corresponding to the main soldering mechanism and the backup soldering mechanism, and the feedback components are light and / or sound feedback devices.

[0010] Preferably, one side of the backup soldering mechanism is provided with a second visual self-inspection component and an alarm component that are electrically connected to the main control unit. When the second visual self-inspection component detects that the workpiece after resoldering is still unqualified, the alarm component is controlled by the main control unit to issue an alarm.

[0011] The beneficial effects of this utility model are: the quality of soldering is detected by the first vision self-inspection component, and when a soldering abnormality is detected, the workpiece is promptly transferred to a backup station by the workpiece transfer mechanism for resoldering by the backup soldering mechanism. The abnormal solder joints during the main soldering are processed in a secondary manner, which improves the soldering quality. At the same time, no manual transfer is required, which reduces the error in soldering position caused by the movement of the workpiece. Attached Figure Description

Detailed Implementation

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below with reference to specific illustrations.

[0016] Reference Figures 1-4 As shown, a dual-station automatic soldering machine with solder joint quality self-inspection function includes a frame 1. Two multi-axis motion mechanisms 2 are mounted on the frame 1, and each of the two multi-axis motion mechanisms is equipped with a main soldering mechanism 3 and a backup soldering mechanism 4. Each multi-axis motion mechanism 2 includes an X-axis linear slide 21, a Y-axis linear slide 22 sliding on the X-axis linear slide 21, and a Z-axis linear slide 23 slidably connected to the Y-axis linear slide 22. A mounting bracket 11 is slidably connected to the X-axis linear slide 21. Both the main soldering mechanism 3 and the backup soldering mechanism 4 are mounted on... On the mounting bracket 11, the multi-axis motion mechanism 2 drives its movement to perform soldering operations on the workpiece. The main soldering mechanism 3 and the backup soldering machine are both known soldering equipment, including a solder head for performing the soldering operation, a solder feeding component for providing solder material, and a heating device for heating the solder head, etc. All of the above are existing technologies and will not be described in detail here. Those skilled in the art should know that it also includes a first vision self-inspection component 5, a workpiece transfer mechanism 6, and a main control unit 7. The first vision self-inspection component 5 is located on one side of the main soldering mechanism 3. The system performs quality inspection on the solder joints completed at the main soldering station. The workpiece transfer mechanism 6, mounted on the frame 1, transfers workpieces from the main soldering station to a backup soldering station. The first visual self-inspection component 5 can also employ currently available technologies, including an industrial camera, a light source, and an image processing unit. The industrial camera captures images of the solder joints after soldering at the main soldering station. The light source provides sufficient and uniform illumination to ensure image clarity. The image processing unit analyzes the captured images to determine if there are any quality issues such as cold solder joints, abnormal solder levels, or short circuits. The system detects the problem and transmits the detection result signal to the main control unit 7. When the main control unit 7 receives a signal from the first vision self-inspection component 5 that the solder joint quality of the main soldering station is abnormal, it controls the workpiece transfer mechanism 6 to move the workpiece to the backup soldering station. At the same time, it controls the backup soldering mechanism 4 of the backup soldering station to start and resolder the abnormal solder joint of the workpiece, thereby reducing the probability of defective solder products. Furthermore, the workpiece is transferred through the workpiece transfer mechanism 6, eliminating the need for manual handling of the workpiece and reducing welding errors caused by inaccurate workpiece positioning.

[0017] Reference Figure 4As shown, the main control unit 7 further includes a counting module 71 and an alarm module 72. The counting module 71 is used to count the number of times the standby soldering station is started within a unit time. When it exceeds a preset threshold, the control system triggers the alarm module 72 to issue an alarm signal. For example, if the number of times the standby soldering mechanism 4 is started within a unit time is set to 3, and the number of times the standby soldering mechanism 4 is started within this time range is greater than 3, it indicates that the main soldering mechanism 3 is frequently malfunctioning and there may be a larger malfunction in the future. It is necessary to take timely measures to issue an alarm through the alarm module 72 to remind personnel so as not to delay subsequent production.

[0018] Reference Figures 1-2 As shown, furthermore, when the main soldering mechanism 3 experiences a soldering abnormality, the workpiece will be transferred to the backup soldering mechanism 4 via the workpiece transfer mechanism 6. The workpiece transfer mechanism 6 includes a placement tray 61 slidably connected to the frame 1 and a telescopic member 62 located on the frame 1 with its movable end connected to the placement tray 61. The telescopic member 62 can be an electric telescopic rod electrically connected to the main control unit 7, etc. The placement tray 61 is used to place the workpiece. The workpiece is moved from the main soldering station to the backup soldering station for resoldering by the movement of the placement tray 61 driven by the telescopic member 62, without the need for personnel to manually change the position of the workpiece.

[0019] The main control unit 7 also includes a synchronization control module 73. The synchronization control module 73 is configured such that when the main control unit 7 controls the multi-axis motion mechanism 2 of the main soldering mechanism 3 to perform the soldering action, it synchronously sends the same motion parameter command to the multi-axis motion mechanism 2 of the backup soldering mechanism 4 to achieve synchronous action between the two. For example, when the multi-axis motion component on the main soldering mechanism 3 moves and drives the solder head to move to a certain angle, the corresponding multi-axis motion mechanism 2 of the backup soldering mechanism 4 will also synchronously drive the solder head on the backup soldering mechanism 4 to move to the same angle. When the workpiece transfer mechanism 6 moves to the backup soldering station, the backup soldering mechanism 4 can resolder the points on the workpiece where the soldering abnormality occurred without having to re-find the points.

[0020] Reference Figure 1 As shown, furthermore, the frame 1 is equipped with feedback components 8 corresponding to the main soldering mechanism 3 and the backup soldering mechanism 4. The feedback components 8 are light and / or sound feedback devices, such as warning lights and buzzers. When the main soldering mechanism 3 or the backup soldering mechanism 4 is working, feedback is generated through the corresponding feedback components 8 so that personnel can know from a distance which soldering mechanism 4 is working. For example, the main soldering mechanism 3 corresponds to a red warning light, while the backup soldering mechanism 4 corresponds to a green warning light, so that they can be distinguished.

[0021] Reference Figure 2As shown, further, a second visual self-inspection component 9 and an alarm component 91 are provided on one side of the backup soldering mechanism 4, which are electrically connected to the main control unit 7. When the second visual self-inspection component 9 detects that the workpiece after resoldering is still unqualified, the alarm component 91 is controlled by the main control unit 7 to issue an alarm. The second visual self-inspection component 9 is the same as the first visual self-inspection component 5, which performs quality inspection on the solder joints after resoldering. When it is detected that the workpiece is still unqualified after resoldering, an alarm is issued through the alarm component 91 to remind personnel that this solder product is a defective product so that it can be rejected or marked in time. The alarm component 91 can use a different warning light or buzzer than the feedback component 8 for easy distinction.

[0022] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
